Many thanks for the feedback lads, they were all done with Turbocad V15 Platinum, and have greatly improved since using the ray cube with cube and also plain background and environment. I have just updated these images, as I have had a request for their use on the Turbocad Facebook Gallery. Sorry that I could not provide larger images, as I actually have the full size prints for sale.
Hammer, I am building up a series of prints for sale, and then at some time in the future, I hope to produce the sculptures.
Brad, The Mother Earth Sculpture is 7.5" x 8.6" x 8.7" and the Unity Sculpture is 7.7" x 7.7" x 10". Both of the sculptures are modelled at Acis Quality or Higher, and 6 decimal places for Space units , and 6 decimal places for angles. Basically, they could be 1000 times bigger to a thousandth of an inch (I think).
